CONNECTING- BOD SAFETY LOOiP.

Application filed November 27, 1925. Serial No. 71,648.

This invention relates to new and useful improvements in safety loop supports or hangers for brake beam connecting rods and has for its object the PI'OVISIOII of a safety loop support adapted to be attached to a carrying member and provided with a depending portion terminating in a loop adapted to encircle or partially embrace the bottom connecting rod of the brake gear,-

the end or ends of said safety loop'support being adapted to enter interlock ng engage-v ment with each other or with said. carrying member to render said support immovable on said carrying member.

7 Further objects of the invention are to provide a safety support or hanger having one-portion formed to detachably embrace a carrying member, such as a brake beam part, or spring plank and having a depending portion looped to extend under and upwardly on each side ofa bottom connectmg rod for catching and supporting said rod in case of its disengagement at either one of its ends.

Still further objects of the invention are to form the upper portion of said safety support or hanger with a benttermmal portion or portions so as to lock said loop safety support or hanger against accidental displacement from said carrying member With these and other objects in v1ew, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which-- Figure l :is a vertical cross section through a portion of a car truck and showing the safetyloop -carried by a brake beam 'pa't and engaging the bottom connecting ,ro I

Figure 2 is a view taken on line 2-2 of Figure 11 is a vertical section taken on line 1111 of Figure 10.

Figure 12 is another modified form of safety support. and hanger carried by the compression and tension members of the brake beam and having its 'rod en aging port on formed in the shape of a closed ring.

Figure 13 is a sectiontaken on lines 1313 of F i ure 12. Referring y numerals to the accompanying drawings and more particularly to Figures 1 and 2, 10 indicates the spring plank of a car truck and 11 indicates a brake beam consisting of a compression member 12, tension member 14,.and strut 15. A brake lever 16 is pivotally mounted in the strut andhas its lower end pivotally connected to one end of a bottom connecting rod 17 which is horizontally disposed under the spring plank and the brake beam and has its oppos'ite end connected to a brake gear connection similar to the one shown in the drawmgs. All of the parts are of any approved construction and are standard equipment of railway cars. I y

In order to prevent said bottom brake rod from dropping to the ground in case one of its ends becomes accidentally disengaged from its respective lever or connection, a safety support or hanger 18 is arranged on.

a suitable carrying or supporting member such as a brake beam part, in the present instance compression member 12, and said, hanger is provided with a depending portion 19 terminating in a loop or eye 2% which encircles said brake rod and normally is spaced therefrom so as not to" impede its operative movements and is adapted to form a support therefor in case of displacement thereof.

, The compression member engaging por tion 21 is bent horizontally over said memher and then downwardly and has its end hooked as indicated at 22 and bent under said compression member so as to engage shank portion 23 of said support. In this manner, the support or hanger is locked in position on the compression member and is held against movement longitudinally of said member by the resiliency of said supportmember, portion 21 and shank 23 being stressed when interengaged with each other.

In the form shown in Figure 3. hanger 24 is provided with a loop for encircling the" Y is formed with a loop 29 for engaging bottom connectin rod 17 and one leg of said member exten s upwardly and isbent laterg ally as indicated at. 30 and bears against the upper face of compression member 12. The

other leg is bent laterally as at 31 aiid extends under the compression member 12 and I upwardly on "opposite side thereof and is rebent to form ashouldered portion 32 which is adapted to fit between the spaced flanges 12" of member 12. The extreme end of this rebent portion projects upwardly to one side of compression member l2 as indicated at 33 and is adapted to be engaged by the hooked portion 30" of laterally disposed portion 30. By interengaging the rebent por tion of the 00p support with the flanges of the carryin member, said loop or hanger is securely he (1 against movement in either direction.

In the form-shown in Figure 5, the safety support or hanger 34 is provided with a U- shape portion 35 for engagin the bottom connecting rod 17 The legs ot this portion extend upwardly and are bent at a point below the carrying member 12 so as to cross each other and extend upwardly on the opposite sides of said member as shown at 36. These'portions 36 are bent at right angles to bear against the upper face of carrying member 12 as shown at 37 and have their ends bent at an angle toportions 37 to extend downwardly on each side'of said carrymg member 12. \Vhen placed in-position, portions. 36 are stressed and are spring-held in engagement with the carrying member,

thereby preventin rattling of the support and maintainingatfie latter in position.

In the form shown in Figures 6 and'7, the hanger 38 has its upper portions bent as mdicated at 39 to beer at a plurality of points against the peripheral face of a carrymg member, which in the present instance is circular in cross section, and the extremities of portions 39 are rebent to form interlocking en agement as indicated'at 40.

t "e form shown in Figure .8, one leg of loo member/41 extends upwardly to one ,sidelo carrying member 12 and is bent horizontally as indicated at 42 over said member 12 and has a rebent portion" 43 which bears v against the underside of the u per flange of member 12. The other leg 0 said member extends upwardly to the opposite side of saidmember 12 for engaging the edge of the lower fiangeand terminates in a hook 44 which is adapted to engage eye 45, which latter is formed in the extremity of por-' tion 43. f

brake be'am. Portions resilient so as to engage the respective supher 12 and terminates ina rebentport-ion 49 which bears} against the underside of the upper flange of said member 12. A bend 50 I ormed mthe shank of member 46 to increase the reslliency of sand member so that sufficient pressure. is exerted agamst said supporting member- 12 by said member 46 to prevent movement or vibration of supporting member 46.

In the form shown in Figures 10 and 11-, a member 51 is formed of a single piece of material, preferabl y circular in cross section,

and is provided with a portion 52 for surrounding the bottom connecting rod 17 One end of member 51 is bent rearwardly and terminates in ap rtion 53 for partially engaging com )ICSSIOI] member 12 while the of member 51 is bent downterminates in a portion 54 for the tension member of the 53 and 54 are formed opposite en wardly and partially engaging porting members under spring pressure.

In the modified form shown in Figures 12 and 13 member 55 instead of being formed of a single piece of wire or wood is formed of a casting or forging and consists of ,a longitudinally disposed portion 56 theends of which terminate in portions 57 and 58 for engaging the compression member 12 and loo tension member 14, respectively, and is provided with a depending portion 59 termi-' ating in a closed ring 60 through which-the bottom connection rod 17 is adapted to operate.
